Genetinių veiksnių įtaka kiaulių kraujo biocheminiams rodikliams / The influence of genetic factors on blood biochemical parameters in pigs

Smilgevičiūtė, Simona 16 July 2014 (has links)
Darbo tikslas – Išanalizuoti genetinių veiksnių įtaką kiaulių kraujo biocheminiams rodikliams. Darbe išanalizuota kraujo biocheminių rodiklių priklausomybė nuo kiaulių veislės ir lyties. Tiriamųjų kiaulių kraujo biocheminiai rodikliai palyginti su sveikų kiaulių kraujo biocheminių rodiklių norma. Kiaulių kraujo serumo biocheminiai tyrimai buvo atliekami naudojant automatinį biocheminį analizatorių SELECTRA Junior (Nyderlandai, 2006). Tiriamųjų kiaulių grupės suformuotos AB „Kiaulių veislininkystė― kontrolinio penėjimo tvarte. Nustatyta, kad kraujo biocheminiams rodikliams įtakos turi kiaulių veislė. Tarp eksperimentinių kiaulių grupių buvo pastebėti ţenklūs šarminės fosfotazės (ALP) bei mineralinių medţiagų koncentracijos svyramai, ypač vario, geleţies ir natrio. Taip pat nustatyta, jog kiaulių kraujo biocheminiams rodikliams įtakos turi ir jų lytis. Labai ţenkliai skyrėsi kreatinino koncentracija: ji buvo aukštesnė kiaulaičių kraujyje. Šarminės fosfotazės koncentracija kur kas didesnė kastratų kraujyje. Taip pat nustatyti ir ţymūs kai kurių mineralinių medţiagų koncentracijos pokyčiai tarp lyčių, ypač geleţies. Remiantis sveikų kaulių kraujo biocheminių rodiklų normomis, nustatyta, jog kai kurie tiriamųjų veislių kraujo biocheminiai rodikliai neatitinka normos. Viršijamos kai kurių fermentų koncentracijos kraujyje. / The aim of this research - to analyze the influence of genetic factors on blood biochemical parameters in pigs. In this work was analyzed blood biochemical parameters impact from pigs breed and gender. The blood biochemical parameters of investigative pigs was compared with norm of healthy pigs blood biochemical parameters. Biochemical research of pigs blood serum was made by using automatical biochemical analyzer SELECTRA Junior ( Netherlands , 2006). Groups of pigs was formed in barn of controlling fattening AB „Kiaulių veislininkystė―. Ascertained that breed of pigs have influence for blood biochemical parameters. Among the experimental groups of pigs were observed significant levels of alkaline phosphatase ( ALP) and mineral concentration swings , especially copper , iron and sodium . Also ascertained that gender of pigs have influence for blood biochemical parameters. Significantly different was creatinine concentration: it was higher in the blood of gilts. Alkaline phosphatase is much higher in the blood of the castrates. Also ascertained significant changes to some mineral concentration, especially iron, between genders. Based on healthy pigs blood biochemical rates ascertain that blood biochemical parameters of some investigative varieties contravene norm. Concentration of some enzymes in blood were exceeded.

Avaliação in vivo da qualidade protéica da soja Geneticamente modificada / In vivo evaluation of protein quality of genetically modified soy

Giora, Cintia Gisela Bezuti 14 April 2004 (has links)
A soja geneticamente modificada tolerante ao herbicida glifosato foi testada em ensaio nutricional. A qualidade protéica da soja foi avaliada durante 14 dias de experimento com ratos machos tipo Wistar recém desmamados. Além de um grupo controle aproteico, quatro dietas testadas continham cerca de 10% de proteínas de diferentes fontes: caseína, soja comercial, soja parental e soja GM. Resultados similares entre os grupos demonstraram o baixo aproveitamento da proteína ingerida, conforme esperado para todas as dietas com soja não suplementadas com metionina e expressos pelos valores de PDCAAS. As análises hematológicas realizadas demonstraram a síntese comprometida de células eritrócitárias e imunológicas nos mesmos grupos experimentais. Este comportamento fisiológico dos animais indica que a ingestão da variedade GM não causou diferença significativa no desenvolvimento dos animais entre as três amostras de soja ensaiadas e tampouco foram observados efeitos adversos em órgãos dos animais e nos parâmetros químicos analisados. / A glyphosate tolerant soybean obtained by genetic modification was tested on a nutritional essay. The quality of the soy protein was assessed by a 14-day long experiment with Wistar male rats, three weeks old. Besides the control free protein group, four different diet groups containing about 10 % protein were pooled out: casein, commercial, parental and GM soybeans. Similar results showed the regular low biological value of the consumed soy proteins not supplemented by methionine displayed by PDCAAS values. The hematological analysis pointed to a commitment of the synthesis of erythrocytic and immunologic cells at the experimental soy groups. The overall behavior of the animals indicate the ingestion of the GM variety of soybean did not cause significant differences for the rat development when compared to the other soybean groups, neither side effects on inner organs and chemical analyzed parameters.
